Abstract Whilst a plethora of literature has viewed technological progress as one of the critical influencing factors in relation to energy consumption and CO 2 emissions, little effort has been made to identify the sectoral differences in the relationship between technological progress and CO 2 emissions. Thereby, this paper remedies the inadequacies in the extant literature by empirically investigating the impact of technological progress on CO 2 emissions, specifically taking into account its heterogeneous effect in various economic sectors. This paper first decomposes the effect of technological progress as taking place in heavy industry, in light industry, in construction industry, and in service industry. A panel quantile regression approach and a balanced city panel data model are then applied, covering the period 2001–2013 in China. The empirical results show that technological progress in heavy industry and light industry surprisingly facilitates a higher level of CO 2 emissions, despite its prominent contribution to energy efficiency improvement. Meanwhile, as distinct from the effect it shows in the heavy and light industries, technological progress in construction and service industries exerts a negative effect on CO 2 emissions. Additionally, this paper further discovers that the strength of the multiple impacts of technological progress also varies with the level of emitters. By studying the heterogeneous effect brought about by technological progress in different economic sectors and emitters, this paper provides a comprehensive understanding of the relationship between CO 2 emissions and technological progress. Highlights • The study considers the sectoral and scale heterogeneity of technological progress in relation to CO 2 emissions. • We apply a panel quantile regression approach to balanced city-level panel data. • Technological progress within different economic sectors exerts different effects on CO 2 emissions. • The role of technological progress in moderating energy intensity varies across emitters.

As a good power supplement form of super power and large-scale energy base, distributed energy has the characteristics of less investment and flexible power generation. Facing with the double pressure of the sustainable development of energy use and environmental protection, it has become an efficient solution to meet the demand of load growth, reduce environmental pollution and improve the comprehensive utilization of energy and the reliability of power supply. However, the development of distributed energy starts relatively late in China and confronts many difficulties. So this paper analyzes the present development situation and existing problems of the distributed energy in China. Then it elaborates from the aspects of policies and regulations, technical specifications, price policy and grid-interconnection codes. At last, this paper puts forward relevant policy suggestions of the guarantee mechanism of distributed energy. This paper argues that, with the attention of the development of distributed energy increasing, a series of policies to promote the construction and interconnection of distributed energy will be introduced, and distributed energy will get scaled development in China.

The main goal of this paper is to argue for the necessity and significance of studying the distributional employment impacts of renewable and new energy development (RNE). Based on the comprehensive review of the methodology and conclusions of existing literatures, this paper builds up an extended input–output model to study RNE’s distributional employment impacts on gender and personnel structure. The case study of China׳s power sector in this paper affirmed earlier doubts that RNE development will indeed aggravate the gender inequality problem and add to the level of mismatch between the structure of labor demand and supply, causing structural unemployment problems. The quantitative analysis in this paper outlined here implies that from 2011 to 2020 the development of RNE will bring about 7 million employment gains, but only 81.8% of which can be realized due to the mismatch problem. The study of China may alert other countries to be less-optimistic about RNE’s employment impacts and reaffirm the need to carry out the distributional employment impacts analysis. This paper concludes with policy suggestions such as providing suitable training and equal promotion opportunities for women, offering courses and vocational trainings to RNE-related majors, in order to reduce the structural unemployment problem and further speed up the development of RNE.

In the past decades, solar heat for industrial processes (SHIP) have been rapidly developed and applied, and also getting more and more attention all over the world. China is the largest energy consumer with industry accounting for almost 70% of its total energy consumption. Low- and medium-temperature heat takes up 45% of process heat, covering 50–70% of industrial energy consumption, which provides a favorable condition for solar application in industrial processes. China has built developed some demonstration projects to make industrial processes well integrated with solar heating systems. This paper briefly summarizes the status of China's energy consumption, integration of SHIP, as well as available matching solar technologies. Ten typical industrial sectors are selected to specifically describe their potential of SHIP. Moreover, 26 SHIP cases covering the selected 10 sectors are presented by field researches, with capacity of energy saving and emission reduction previously investigated according to their own proportion of SHIP. The potential of SHIP in the 10 sectors are further predicted by optimistically and conservatively making their proportion in SHIP 5.5% and 2% respectively during the period of 2016–2020. The results show that at least 39.40 million tons of coal equivalent and 98.22 million tons of CO 2 emission is expected to be reduced in 2020 in China's all industrial sectors although solar can meet different proportions of heat demand in different industrial sectors.

Electric power industry is a typical industry with high energy consumption and high emissions in China. To relieve the increasing environmental pressures and promote the sustainable development of China’s economy and society, it is urgent to take actions to reduce energy consumption and pollution emissions of China’s electric power industry. In this paper, we first present an overview of the development status of China’s electric power industry, including the total power generating capacity and proportions of different power generation methods, the development of renewable energy power generation, as well as the average utilization hours of different power generation equipment. Then, the development of energy conservation and emissions reduction of China’s electric power industry is studied. The indicators of energy conservation include coal consumption for power supply, power consumption rate of power plants and comprehensive line loss rate; while the contents of emissions reduction include desulfurization, emissions control and the comprehensive utilization of solid waste. Finally, suggestions in five aspects to promote energy conservation and emissions reduction of China’s electric power industry are presented. The five suggestions are improving power generation technologies, expanding renewable energy power generation, optimizing power generation process, strengthening monitoring and regulation, and promoting power generation rights and emissions trading.

All recent analyses acknowledge that environmental resources are in short supply and that it is on them that "carrying capacity" calculations ought to be based. For the specific case of the Chinese society, which is undergoing an unprecedented period of continuous growth, it seems therefore mandatory to alleviate the conflict between high-speed development and available resources. This paper analyzes the variation of the natural resources input into China during years 2000-2007 using the exergy and extended exergy socio-economic metric. Fluxes of materials, labor, capital and environmental remediation expenses were quantified by a numeraire solidly rooted on a second-law metric, so that a new mode of ecological accounting that quantifies both the composition and the proportion of the extended exergy flows can shed light on the total available energy input into the Chinese society. Two new indicators, labor production efficiency and net pro-capite exergy resource input, are proposed to depict the contribution of economic, social and environmental aspects to the usual four production factors and to express the conversion results in transferring efficiency and quantity from material energy to economic output. "Social" extended exergy analysis, applied to each one of the seven sectors of the society, is suggested as an effective method to reveal the energy quality degradation in the resource conversion process at both national and sectoral levels. The comparison of social resource accounting among different societies by using these two indicators may provide useful additional information to evaluate the production conversion coefficients, to assess the environmental impacts and to diagnose possible ecological dysfunctions. In addition, the extended exergy analysis of the Chinese society is helpful in uncovering the long-term resource depletion and promoting efficiency of the resource transformation in the social-economic-environmental system, thus providing a holistic method and a systematic view for decision makers responsible for environmental management.
